The pan and oil pickup is done, so now I moved to the transmission gut swap.
Here's the pickup, I did go back and add a brace after this pic:
After some powerwashing, SD22 transmission is on the right, the 4x4 on the left:
4x4 on the left, SD22 on right:
Free silver paint? This oil doesen't look too good coming out of the SD22, good thing I won't be using these parts again:
Countershaft bearing damage:
This transmission was ridiculously easy to take apart, I feel silly now about asking how hard it would be to do:
A little chewed:
This can't be good either:
Some bonus parts!
The cleaned 4x4 guts hanging out to dry, I had to powerwash after finding some rust that I had to scrape and sand smooth, the assembly wouldn't turn. This transmission has indeed been rebuilt before as the seller told me, it looks like a new front plate and input shaft, plus newer bearings:
You can see the rusty parts, I guess the oil didn't cover these parts while the truck sat for a few years:
More rust, I blew everything dry and splashed on a coat of PB blaster to keep it lubed and wrapped it in a garbage bag to keep it clean before reassembly:
